Glyphosate, which is sold under trade names such as Roundup, is the highest-selling and most heavily used agricultural and domestic herbicide in the world.
It has become so commonplace that supermarkets sell it — despite the fact that, in March 2015, based on mounting research evidence, the World Health Organization upgraded its status to a class-2A carcinogen.
